AP Board 10th Class Physical Science Notes Chapter 3 Refraction of Light at Plane Surfaces AP
Solution: The change in the direction of the path of light, when it passes from one transparent medium to another transparent medium, is called refraction of light. Question: 2 Draw diagrams to show the refraction of light from (i) air to glass, (ii) glass to air.

Ans: - The refractive index of glass relative to water= 9/8, As we all know that refractive index of water relative to glass is = (1/refractive index glass relative to water). So, refractive index will be (1/9/8) = 8/9. 3) The absolute refractive index of water is 4/3. What is the critical angle?

10th Class Physics 6th Lesson Refraction of Light at Curved Surfaces Additional Questions and Answers. Question 1. Derive a relation between refractive indices of two media (n 1, n 2), object distance (u), image distance (v) and radius of curvature (R) for a curved surface. (OR)
Reflection and Refraction with Plane Surfaces
Solution: Since light moves through different media at varying speeds, refraction—or a change in the direction of the path of light—occurs. Except for when I = 0°, a light ray's direction changes as it moves from one medium to another due to a change in speed. Question 6.
